Base review
A free, EVM-compatible Ethereum L2 for deploying and testing Solidity apps.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Base is an Ethereum Layer 2 network incubated by Coinbase and built on the OP Stack. It provides a public, EVM-compatible environment for decentralized applications and smart contracts, with Ethereum L1 data underpinning its L2 blocks. Developers building in Solidity can target Base when they need Ethereum-compatible infrastructure for onchain activity, whether they are testing applications or deploying them for production use.
Base follows a free network model rather than subscription tiers, while onchain transactions require gas fees. Its development path includes Ethereum JSON-RPC access, deployment to Base Mainnet and Base Sepolia, and Foundry support for building and testing contracts. Smart contracts can also connect to external oracle price feeds. These capabilities fit teams that want familiar Ethereum tooling and a focused L2 deployment path through web and API access.
The platform’s scope is concentrated on core Ethereum-compatible development rather than a broad collection of platform services. Its public deployment model is unsuitable for projects that require permissioned networks, and teams seeking a wider feature set may need to compare other blockchain platforms. Choose Base for Solidity applications that benefit from an EVM environment, Ethereum connectivity, and separate Mainnet and Sepolia targets; consider an alternative when network permissions or broader built-in capabilities are central requirements.
Base pros and cons
- Where it wins
- EVM compatibility supports Ethereum-oriented smart-contract development
- Mainnet and Sepolia deployment with Ethereum JSON-RPC access
- Foundry tooling and external oracle price-feed connections
- Where it doesn't
- Onchain transactions require gas fees despite the free network model
- Public deployment does not support permissioned-network requirements
- Core feature set is narrower than broader blockchain platforms
